LOCKING DEVICE.

Application filed November 29, 1915.

To all whom it may concern:

Be it known that I, HENRY ALINDER, a subject of the King of Sweden,residing at Milwaukee, in the county of Milwaukee and State ofWisconsin, have invented a certain new and useful Improvement in LookingDevices, of which the following is a specification.

This invention relates to improvements in the construction of devicesfor detachably securing and locking two elements to each other, theinvention being particularly applicable to timber treating apparatus.

An object of the invention is to provide a locking device which issimple in construction and effective in operation. Another object is toprovide a device for detachably securing two elements to each other,which will permit ready separation of the elements when desired.

The invention consists primarily in forming one of the elements to beconnected with a recess affording a plurality of abutments, and ofproviding the other element with a shoulder engageable with one of theabutments to prevent separation of the elements in one direction,separation of the elements in another direction being prevented by meansof a third element engageable with another of the abutments. While theinvention is especially applicable to devices for locking the bails oftimber treating cars to the bail arms or other elements, it is capableof general application wherever similar conditions of ope ation eXist.

A. clear conception of an embodiment of the invention may be had byreferring to the drawing accompanying and forming a part of thisspecification in which like reference characters designate the same orsimilar parts in the various views.

Figure 1 is an end view of a timber treating car having the inventionapplied theretomv Fig. 2 is an enlarged transverse section through thelocking device showing the same applied to a fragment of a timbertreating bail, the section being taken along the line IIH of Fig. 3looking toward the right.

Fig. 3 is an enlarged end view of the looking device showing the sameapplied to a fragment of a timber treating bail.

Fig. 4 is an enlarged top view of the portion of the locking devicewhich is normally secured to the bail arm.

Specification of Letters Patent.

Patented Apr. 3, 1917..

Serial No. 64,590.

Fig. 5 is an enlarged top view of the lock- 1ng plate.

The timber treating oar disclosed in Fig. 1 consists primarily of a bodyportion 1 having upwardly extending integral bail arms 2, and supportedupon wheels 3 in the usual manner. Each bail comprises essenti ally twosections 5 having looped interlocking upper ends 6, 16, and havingheaded or enlarged lower ends 8. The portion of the car within the bailarms 2 and the bail sections 5 is, during normal operation of thedevice, filled with timber which is prevented from leaving the carduring the process of treating, by means of these elements.

Each of the devices for detachably securing the elements, namely, thebail sections 5 and the bail arms 2, together, comprises an element 4integrally secured to the adjacent bail arm 2 by means of rivets 9passing through alined openings in the bail arm 2 and the projection 10of the element 4:. The element 4: is provided with a recess 13 having alower enlarged portion 15 afl'ording an abutment and having a secondenlarged portion 14 affording a second .butment. The enlarged or headedend 8 of the adjacent bail section 5 is insertible. within the recess 13so that the shoulder formed by the enlargement of the end of the section5 is engageable with the abutment in the recess 13 formed by theenlargement 15 thereof. This formation. of the bailsection 5 and of therecess 13 positively prevents separation of the elements in onedirection, namely, axially of the bail section 5.

A locking plate 7 having its upper portion 11 split at 12 to permitplacing the same around the bail section 5, has a downwardlyextendingportion adapted to enter the enlarged portion 14 of the recess13. With the'locking plate 7 inserted as disclosed in Figs. 2 and 3, thelongitudinal edges of the plate engage the second abutment of the recess13 afforded by the enlarged portion 14: thereof to prevent separation ofthe bail section 5 and the bail arm 2 in another direction, namely,transversely of the axis of the section 5.

In securing a bail section 5 to its bail arm 2, the locking plate 7 mustfirst be raised to a position permitting insertion of the headed end 8within the recess portion 15. After the bail section 5 has been placedin the position disclosed in Fig. 2, the looking plate 7 may be insertedin the recess portion 1a and lowered until stopped by the headed bailend 8, thereby positively look- 'ing the bail section 5 againstdisplacement from within the element 4:- The bail section 5 may bereadily removed by' raising the locking plate 7 and swinging the headedbail end 8 clear of theelement 4 about its upper end 6, 16, as a pivot.The formation of the bail of two sections 5 connected at their upperends 6, l6, permits either simultaneous or successive connection of theheaded bail ends 8 to their respective bail arms 2. The separation ofthe elements may like wise be simultaneous or successive, as desired.

It will thus be noted that the formation of the recess 13' and theengagement of the locking plate 7 andheaded end 8 with surfaces of saidrecess, aifords simple and eflicient means for securing the bail to thebail arm 2 and of readily releasing these elements for separation. g

It will also be noted that the locking plate 7 cooperating with theabutment afiorded by the recess portion 14, affords a second abutmentlocated forwardly of the end of the bail section 5 with reference to thedisplacement of the bail section 5 relative to the element 4 in adirection transversely of the axis of the bail section 5. It should beunderstood that it is not desired to be limited to the exact details ofconstruction herein shown and described, for obvious modifications mayoccur to a person skilled in the art.

It is claimed and desired to secure by Letters Patent,- a

1. In combination, an element having a recess afl'ording an abutment, asecond element insertible in said recess and having a shoulderengageable with said abutment to prevent separation of said elements inone direction, said recess affording a second 7 abutment, and meanssecured to said second element and engageable with said second abutmentto prevent separation of said elements in another direction. 7

2. In combination, an element having a recess enlarged at one portion toform an abutment, a second element insertible in said recess and havingan enlarged portion engageable with said abutment to prevent separationof said elements in one direction, said recess having a second enlargedportion affording a second abutment, and means engageable with saidsecond abutment to prevent separation of said elements in anotherdirection.

3. In combination, an element having a recess affording an abutment, asecond element insertible in said recess and having a shoulderengageable with said abutment to prevent separation of said elements inone direction, and means secured to said second element and affording asecond abutment located forwardly of said second element wit-h referenceto another direction in which separation of said elements is prevented.

4. In combination, an clementv having a recess provided with a pluralityof enlarged portions extending at an angle to each other, a secondelement having an enlarged portion insertible within one of saidenlarged recess portions, and means insertible in the other of saidenlarged recess portions to lock said elements against relativemovement.

5. In combination, an element having a. recess provided with a pair ofenlarged portions extending at an angle to each other, a second elementhaving an enlarged end insertible within one of said enlarged recessportions, and a locking plate having a portion surrounding said secondelement, said locking plate being insertible in the other of saidenlarged recess portions to lock said elements against relativemovement.

6. In combination, an element having a recess provided with a pair ofenlarged portions extending at an angle to each other, a second elementhaving an enlarged end insertible within one of said enlarged recessportions, and a locking plate insertible in the other of said enlargedrecess portions and engageable with a portion of said second elementbeyond said enlarged end to lock said elements against relativemovement.

In testimony whereof, the signature of the inventor is afliXed hereto.
